Abstract A dual nozzle intranasal delivery device has a housing with a cavity for the reception of a container having a pierceable stopper and having a first passage communicating with said cavity. A hollow needle secured in the passage extends into the cavity and is adapted to penetrate the stopper of the container. A pair of substantially parallel spray nozzles communicate with a second passage in the housing. A turret member is rotatably mounted in the housing and has a passage adapted to communicate alternatively with the first and second passages and having an opening for the reception of a syringe nozzle. Through the use of the turret a syringe can be placed in communication with the container and then, by rotating the turret, placed in communication with the second passage to provide for taking liquid from the container and delivering it through the nozzles.
A dual nozzle intranasal delivery device comprising: a housing, said housing having a cavity for the reception of a container having a pierceable stopper and a first passage communicating with said cavity, a hollow needle secured in said passage and extending into the cavity, said needle being adapted to penetrate the stopper of said container, a pair of adjacent nozzles having substantially parallel axes a second passage in said housing communicating with said nozzles, a cylindrical opening in said housing, each of said passages communicating with said opening. a turret member mounted in said cylindrical opening and having a passage of which one end alternatively communicates with the first and second passages and the other end is provided with an opening for the reception of a syringe nozzle whereby a syringe can be placed in communication with the container and then by rotation of the turret placed in communication with the second passage.
